This invention relates tomethods and apparatus for calendering or or rubberized fabric stock. n

. Heretofore, this stock has beencooled as it issues from the calenders or other rubber forming machines either by passing through a tankiof cooling liquid or bypassing over rollers chilled with a refri erant. These devices are not entirely satis actory because of theamount of space required by theformer and theexpensein installation and maintenance of the latter.

The present inventionhas for its object the provision of simple procedure and inexpensive aparatus adapted effectively to cool rubber or rubberized stock issuing from rubber forming machines such as calenders.

, Specifically, the invention is directed to the provision of a cooling mist or spray formed by a moisture-laden air blast directed against it, whereby the cooling is effected mainly by evaporation of the moisture from the surface of the stock ratherthan by conduction.

The foregoing and other objects are obtained by the procedure and the apparatus for carrying out the same which are de; scribed below and illustrated in the accompanying drawings. I

rubberizing. fabric. The stock '11" passes through calendar 10 from a reeling; device 12 and is drawn from the calendarover a forming. rubber Figure 3 is a section on line 3 ofFigure' Referring to Figures 1 vto 3 of the draw-. ings, 10 indicates a calendar such as usedfor vertical series of offset rollers13, 14, 15 and l{gby means of a winding and reeling device i Cooling of the stock 11 is accomplished by Q. the directingiof a moisture laden. air blast against the opposite sides thereof. This is eflected by a cooling device indicated erally'at 17 and directing its blast agalnst roller 13 and by a second similar coolingde vice 18 directing ,its'blast against roller 14:. vDevices 17 and 18 each-include a suitably supported upper pipe 19 havingapertures I through which water can flow and a lower pipe 20 having apertures through which.

blasts of air may be directed into the stream of water from pipe 19 and toward the roller over which the stock 12 is traveling. Beneath pipe 20 there is preferably arranged a blast-directing vane 21 extending in a direction toward the roller on which the stock is to be cooled. Suitable valves, indicated at 22 and 23, may be-employed to control the respective supplies of water and air. I

In the form of the invention shown in Figures 4 and 5, arrangement has been made."

for cooling strip rubber stock 24:, 24 issuing I froma forming machine and being'conduoted therefrom on a belt 25. Cooling devices ema bodying the invention are arranged at26, 26 ,1

on opposite sides of the belt. devices include-an upper water pipe 27,. de-

livering a stream therefrom at 28, and two I,

lower converging air pipes 29, 29 directing blasts of air into the stream at angles from.

opposite sides thereof, the ends of the three pipes preferably being enclosed by a spray directing nozzle piece 30. Control of the water supply may be efiected by a valve 31 an'dof the air supply by avalve 32.

In the use of either form of the invention, 7

the blasts of moisture-laden air are directed against stock, the air serving to convey the water to the stock and to rapidly evaporate the water at the surface of the stock. water continues to evaporate from ,the stock as it passe to the reeling device so that the cooling proceeds from the spray devices to the reeling device over a considerable distance Without necessitating the use of long tanks and refrigerated rollers.

Modifications of the invention may be resorted to Without departing from the spirit thereof or the scope of the appended claim. What is claimed is: v The combination with a rubber forming machine of means for directing a spray or mist of Water against each surface of the stock issuing therefrom.
